A572-50 (A572 grade 50) plate has a higher yield and tensile strength than A36 plate, combined with a lower weight. This steel is a high strength, low alloy steel plate. It offers an optimum combination of strength, weldability and notch toughness. A709 grade 50W carbon steel plate Applications include: bridges, buildings, automotive and truck parts, railroad cars, cargo containers, tote boxes, construction equipment, structural tubing, lighting standards and transmission poles.
Customs statistics show that in the first two months of 2020 year, Tianjin's imports and exports to the EU, South Korea, Japan, the United States and other traditional trading partners declined, and imports and exports to ASEAN were 12.7 billion yuan, an increase of 7.8%, accounting for 12.8%. Among Tianjin's main trading partners, The only company that keeps growing is Tianjin's second largest trading partner. During the same period, Tianjin's imports and exports to the countries along the “Belt and Road” were 25.3 billion yuan, an increase of 6.2%, accounting for 25.5% of the city ’s total foreign trade import and export value, and an increase of 3.9% compared to the same period last year.
Advantages of A709 grade 50W carbon steel plate: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of A709 grade 50W carbon steel plate steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
